1-check battery using multimeter (voltage should be around 3.8~3.7 on DCV range) 2-if battery is not as mentioned above connect it to a power supply rated at 3.8v (+to+ & -to-) for about 1 min then measure its voltage again. 3-if battery voltage increased then it is ok and accepting charging but it was flat dead. 4-if not then battery is damaged and need replacement. you can also try another procedure as follows: 1-plug your charger in wall outlet, don't connect its usb to your phone yet. 2-press and hold power button 3-while like that....plug in charger usb to phone socket 4-release power button on sight of starting screen

did you try to start it up again after giving it some time to cool down?...my guess is "the cpu cooling heat sink fins are blocked by a mix of hair\lint\dust" so you'll need to tear it down and clean it properly then reassemble it back again and attach it to the cpu using a fresh new thermal paste...don't put too much just use a thin lines shaped as X shape on top of your cpu.

sorry to hear that, but i recommend that you get help through a pro on that, he'll be a far better help than any advice or repairing steps told to you over here, this kind of work needs a lot of visual inspections and tests, try to find a friend or so.
